The d.r’s of normal to the plane through 
which makes an angle 
with plane 
, are
A
B
1,1, 
C
1, 1, 2
D
Text Solution
Verified by ExpertsThe correct answer is:
B
The plane by intercept form is 
.
D.r’s of normal are 1,1, 
and of given plane are 1,1, 0. Now, 
⇒ ⇒ 
⇒ ⇒ 
⇒ ⇒ 
∴ ∴ D.r’s of required normal are 1, 1, 
.
